How to use this site
A short map of what's here and how your data is handled.
What each section does
- Growth Center — track height/weight/head circumference and compare to official reference tables and percentile curves.
- Development observation — an official-source-based checklist to gently observe milestones, not a test.
- Health checkups & vaccinations — Korea's national schedule, based on your child's birth date.
- Play by age — age-appropriate play ideas with safety notes.
- Care roadmap — oral care, toilet training, media use, hygiene, and vision/hearing guidance by age.
- Fun Time — light, local-only play-preference features (not personality tests).
Where your data goes
Everything you type — birth date, growth measurements, checklist answers, play notes, fun-feature results — is saved only in this browser's local storage. Nothing is sent to a server, and nothing syncs across devices. Clearing your browser data removes it. See our Privacy Policy for details.
What's in English vs. Korean-only
This English section currently covers informational and policy pages, the growth average table, the measurement guide, and an overview of Fun Time. The interactive tools themselves (entering data, taking the development checklist, playing the fun features) are still Korean-only. We're translating and reviewing more pages over time — unreviewed machine translations are never published.
